What is the mass of 0.2 mole of oxygen atoms.
Please answer step by step.

Moles is the unit which measures the amount of substance in the System International (SI). A mole is the amount of substance that contains the same amount of substance as the amount of substance exactly in exactly 12 g of carbon-12. C-12 is the standard to measure moles.

I have attached the Equations for moles.

For this question we will use the formula,

Rearrange the equation,

Given:

          Moles = 0.2

          Molecular Mass of Oxygen Atom(Not molecule) = 16

Thus,

The mass of 0.2 moles of oxygen atom is 3.2 grams.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
